Experimental opto-electronic model of ceilometer for cloud base height measurement

摘要

Experimental determination of cloud base height (CBH) by a passive monostatic method by means of opto-electronic ceilometer model was carried out. The model of a ceilometer is two black-and-white CCD-cameras having closest sighting lines. Focal lengths for optical systems of used television cameras were selected for the possibility of measuring the CBH from 50 to 1500 m. Obtained by cameras the pictures with different scale images of selected for measure of cloudiness fragments are digitized on computer and are processed. The algorithm for determining the CBH using the proposed model of ceilometer is described and results of experimental measurements are shown.
